I always do 1-2mg doses each time I take my bupe, but I slam it too.. so it wears off much faster than sniffing, sublingual, or any other ROA would, for the most part.. lasts a good 3-6 hours, then I start to feel the WD slowly creep in and I do another 2mg quarter of my bupe(subutex). I believe that less IS more with bupe, no doubt.. sorry i am just kind of scanning this thread, read the first post the OP originally posted, and scanned the rest, i am kind of in a hurry.. just stating my opinion on it.. At doses less than 2mg or just 2mg, i find bupe to be MUCH more therapeutic than at doses 3mg plus... A lot of my buddies, claim that more is more, with bupe to them, just like any other opioid would be.. but i will always argue with them, just to try doing less, and see what happens.. Some did believe me, and read up on the whole less is more theory, and now take way less.. some are very close minded and didn't give it a try at all, claiming 4mg at a time, works way better! and they take like 16-24mg a day... which is wayyyy too much.. Sorry if i am not on the same page, or something with this post.. but being on bupe as long as i have, i just wanted to chime in, with my opinion and experience.. The ROA you take bupe has a lot to do with it too!
